This study concerns students’ ideas about the superposition of electric fields. Two paper‐and‐pencil questionnaires were given to university students to investigate possible obstacles to a correct use of this principle.

The results confirm an expected difficulty about Gauss's theorem, i.e., the idea that only ‘internal’ charges create a field on a given closed surface. Another more surprising finding is that students are reluctant to admit that a field can penetrate into, or go out of, an insulator, particularly because ‘charges cannot move’.

These first findings are discussed in connection with common features of students’ reasoning about mechanics and about multivariable problems. Some directions of future research are proposed.  相似文献

Background: Inquiry-based science education (IBSE) is suitable to teach scientific contents as well as to foster scientific skills. Similar conclusions are drawn by studies with respect to scientific literacy, motivational aspects, vocabulary knowledge, conceptual understandings, critical thinking, and attitudes toward science. Nevertheless, IBSE is rarely adopted in schools. Often barriers for teachers account for this lack, with the result that even good teachers struggle to teach science as inquiry. More importantly, studies indicate that several barriers and constraints could be ascribed to problems teacher students have at the university stage.

Purpose: The purpose of this explorative investigation is to examine the problems teacher students have when teaching science through inquiry. In order to draw a holistic picture of these problems, we identified problems from three different points of view leading to the research question: What problems regarding IBSE do teacher students have from an objective, a subjective, and a self-reflective perspective?

Design &; method: Using video analysis and observation tools as well as qualitative content analysis and open questionnaires we identified problems from each perspective.

Results: The objectively stated problems comprise the lack of essential features of IBSE especially concerning ‘Supporting pupils’ own investigations’ and ‘Guiding analysis and conclusions.’ The subjectively perceived problems comprise concerns about ‘Teachers’ abilities’ and ‘Pupils’ abilities,’ ‘Differentiated instruction’ and institutional frame ‘Conditions’ while the self-reflectively noticed problems mainly comprise concerns about ‘Allowing inquiry,’ ‘Instructional Aspects,’ and ‘Pupils’ behavior.’

Conclusions: Each of the three different perspectives provides plenty of problems, partially overlapping, partially complementing one another, and partially revealing completely new problems. Consequently, teacher educators have to consider these three perspectives.  相似文献

Background: Past studies have shown significant associations between students’ conceptions of learning science and their science learning self-efficacy. However, in most of the studies, students’ science learning self-efficacy has often been measured by a singular scale.

Purpose: Extending the findings of these studies, the present study adopted a multi-dimensional instrument to assess Taiwanese high school students’ science learning self-efficacy and investigate the relationships with their conceptions of learning science.

Sample: A total of 488 Taiwanese high school students (265 male and 223 female) were invited to participate in this survey.

Design and method: All the participants responded to the Conceptions of Learning Science (COLS) questionnaire regarding ‘Memorizing’, ‘Testing’, ‘Calculating and practicing’, ‘Increase of knowledge’, ‘Applying’ and ‘Understanding and seeing in a new way’ and the Science Learning Self-Efficacy (SLSE) instrument, including ‘Conceptual understanding’, ‘Higher-Order cognitive skills’, ‘Practical work’, ‘Everyday application’ and ‘Science communication’.

Results: The path analysis results derived from the structural equation modeling method indicated that, of all five SLSE dimensions, the ‘Understanding and seeing in a new way’ COLS displayed as a positive predictor, while the ‘Testing’ COLS was a significant negative predictor. The ‘Applying’ COLS item can only positively contribute to the SLSE dimensions of ‘Higher-Order thinking skills’, ‘Everyday application’ and ‘Science Communication’.

Conclusions: In general, students in strong agreement with learning science as understanding and seeing in a new way or the application of learned scientific knowledge are prone to possess higher confidence in learning science. However, students who consider learning science in terms of preparing for tests and examinations tend to hold lower science learning self-efficacy.  相似文献

ABSTRACT

Background: Physics is often seen as a discipline with difficult content, and one that is difficult to identify with. Socialisation processes at the upper secondary school level are of particular interest as these may be linked to the subsequent low and uneven participation in university physics. Focusing on how norms are construed in physics classrooms in upper secondary school is therefore relevant.

Purpose: The purpose of this paper is to identify discursive patterns in teacher–student interactions in physics classrooms.

Design and methods: Three different physics lessons with one class of students taught by three different teachers in upper secondary school were video-recorded. Positioning theory was used to analyse classroom interaction with a specific focus on how physics was positioned.

Results: We identified seven different storylines. Four of them (‘reaching a solution to textbook problems’, ‘discussing physics concepts in order to gain better understanding’, ‘doing empirical enquiry’ and ‘preparing for the upcoming exam’) represent what teaching physics in an upper secondary school classroom can be. The last three storylines (‘mastering physics’, ‘appreciating physics’ and ‘having a feeling for physics’) all concern how students are supposed to relate to physics and, thus, become ‘insiders’ in the discipline.

Conclusions: The identification and analysis of storylines raises awareness of the choices teachers make in physics education and their potential consequences for students. For example, in the storyline of mastering physics a good physics student is associated with ‘smartness’, which might make the classroom a less secure place in general. Variation and diversity in the storylines construed in teaching can potentially contribute to a more inclusive physics education.  相似文献

Abstract

Three strategies for teaching and learning about photosynthesis are described and criticized on the grounds that none of them promotes understanding of photosynthesis as a carbohydrate‐producing process in a way which can be related to students’ prior knowledge. The ‘guided discovery’ strategy, which currently predominates in classrooms, involves experimental procedures which frequently distract students from the crucial aspect, i.e., starch production, but leaves their prior understandings largely undisturbed. An ‘element analysis’ strategy and a ‘meaning of plant food’ strategy are also assessed.  相似文献

ABSTRACT

Michael Young’s work is central to debates about knowledge and the school curriculum. In recent years he has renounced his early argument that school subjects represent the ‘knowledge of the powerful’, arguing instead that access and equality for all students are dependent on ensuring that all get access to ‘powerful knowledge’. This paper provides an interpretation of Young’s work.  相似文献

Cooperative learning is an active learning approach in which students work together in small groups to complete an assigned task. Students commonly find the subject of ‘physical and chemical changes’ difficult and abstract, and thus they generally have many misconceptions about it.

Purpose

This study aimed to investigate the effects of jigsaw cooperative learning activities developed by the researchers on sixth grade students’ understanding of physical and chemical changes.

Sample

Participants in the study were 61 sixth grade students in a public elementary school in Izmir, Turkey.

Design and methods

A pre-test and post-test experimental design with a control group was used, and students were randomly assigned to the experimental and control groups. Instruction of the subject was conducted via jigsaw cooperative learning in the experimental group and via teacher-centered instruction in the control group. During the jigsaw process, experimental group students studied the subjects of changes of state, changes in shape and molecular solubility from physical changes, and acid–base reactions, combustion reactions and changes depending on heating from chemical changes in their jigsaw groups.

Results

The concept test results showed that jigsaw cooperative learning instruction yielded significantly better acquisition of scientific concepts related to physical and chemical changes, compared to traditional learning. Students in the experimental group had a lower proportion of misconceptions than those in the control group, and some misconceptions in the control group were identified for the first time in this study.

Conclusions

Jigsaw cooperative learning is an effective teaching technique for challenging sixth grade students’ misconceptions in the context of physical and chemical changes, and enhancing their motivation, learning achievements, self-confidence and willingness in the science and technology lesson. This technique could be applied to other chemistry subjects and other grade levels.  相似文献

Background: Teacher knowledge continues to be a topic of debate in Australasia and in other parts of the world. There have been many attempts by mathematics educators and researchers to define the knowledge needed by teachers to teach mathematics effectively. A plethora of terms, such as mathematical content knowledge, pedagogical content knowledge, horizon content knowledge and specialised content knowledge, have been used to describe aspects of such knowledge.

Purpose: This paper proposes a model for teacher knowledge in mathematics that embraces and develops aspects of earlier models. It focuses on the notions of contingent knowledge and the connectedness of ‘big ideas’ of mathematics to enact what is described as ‘powerful teaching’. It involves the teacher’s ability to set up and provoke contingent moments to extend children’s mathematical horizons. The model proposed here considers the various cognitive and affective components and domains that teachers may require to enact ‘powerful teaching’. The intention is to validate the proposed model empirically during a future stage of research.

Sources of evidence: Contingency is described in Rowland’s Knowledge Quartet as the ability to respond to children’s questions, misconceptions and actions and to be able to deviate from a teaching plan as needed. The notion of ‘horizon content knowledge’ (Ball et al.) is a key aspect of the proposed model and has provoked a discussion in this article about students’ mathematical horizons and what these might comprise. Together with a deep mathematical content knowledge and a sensibility for students and their mathematical horizons, these ideas form the foundations of the proposed model.

Main argument: It follows that a deeper level of knowledge might enable a teacher to respond better and to plan and anticipate contingent moments. By taking this further and considering teacher knowledge as ‘dynamic’, this paper suggests that instead of responding to contingent events, ‘powerful teaching’ is about provoking contingent events. This necessarily requires a broad, connected content knowledge based on ‘big mathematical ideas’, a sound knowledge of pedagogies and an understanding of common misconceptions in order to be able to engineer contingent moments.

Conclusions: In order to place genuine problem-solving at the heart of learning, this paper argues for the idea of planning for contingent events, provoking them and ‘setting them up’. The proposed model attempts to represent that process. It is anticipated that the new model will become the framework for an empirical research project, as it undergoes a validation process involving a sample of primary teachers.  相似文献

Abstract

The purpose of this study was to ascertain the influence of an extrinsic motivational tool, ‘class-bucks’, on the possibility of improving first year student-teachers’ participation in active learning at Tshwane University of Technology in South Africa. Research participants (n=289) were divided into four classes and engaged in this study during the second and third semester of the course. During the second semester, the students in Class 1 and Class 2 were awarded with ‘class-bucks’ for active participation in lectures, while Classes 3 and 4 were not awarded. Then, during the third semester, the students in Classes 3 and 4 were awarded, while those in Classes 1 and 2 were not. Semester test results and the number of instances of active participation during lectures were recorded and compared to formulate findings and recommendations. The results presented in this article will assist lecturers in valuing an extrinsic motivational tool, ‘class-bucks’, which can be used to encourage active student participation during lectures, thus contributing to the expansion of quality education and improving the student's ability to retain learning content for longer.  相似文献

ABSTRACT

Prismatic refraction is a classic topic in science education. To investigate how undergraduate students think about prismatic dispersion, and to see how they change their thinking when observing dispersed images, five teaching experiments were done and analysed according to the Model of Educational Reconstruction. For projection through a prism, the students used a ‘split image projection’ conceptualisation. For the view through a prism, this conceptualisation was not fruitful. Based on the observed images, six of seven students changed to a ‘diverted image projection’ conceptualisation. From a comparison between students’ and scientists’ ideas, teaching implications are derived for an image-based approach.  相似文献

Background: Alongside academic and vocational goals, schools are increasingly being called upon to address student well-being. Existing evidence suggests that strong relationships and a sense of connectedness in school communities are important for fostering subjective well-being. However, identifying the specific nature of such relational dynamics, and accommodating the ‘personal’ within school cultures increasingly dominated by ‘performance’ narratives, remains a problematic task.

Purpose: This paper draws on Honneth’s recognition theory to offer fresh insight into how relationships act to facilitate and limit the experience of well-being at school. We suggest that such an approach holds considerable potential for developing teachers’ understanding of the tacit and explicit ways they and their students experience being cared for, respected and valued and the ways in which such actions impact on well-being.

Design and methods: The paper reports the qualitative findings from a large mixed-method study, involving students and staff across primary and secondary schools in three regions of Australia. The qualitative phase involved focus groups with 606 primary and secondary students and individual interviews with 89 teachers and principals.

Results: Across the focus groups and interviews, students and teachers placed substantial emphasis on the importance of relationships, while reporting differences in their views about which relationships support well-being. Alongside this, there were differences in the importance teachers and students placed on each of the three strands of Honneth’s recognition theory (translated for this study as being cared for, respected and valued) for influencing student well-being.

Conclusions: The findings affirm the critical role that relationships play in promoting well-being in the context of schools. Using recognition theory to analyse students’ and teachers’ views and experiences of well-being provides much greater insight into how these relationships are enacted – this being through the mutual experience of being cared for, respected and valued – within the context of schools.  相似文献

ABSTRACT

In surveys and semi-structured interviews, Graduate Teaching Assistants (GTAs) discussed the role of reading in their first-year composition (FYC) courses infused with ‘writing about writing’ and ‘teaching for transfer’ perspectives. Three transformative reading lenses played a pivotal role in instructors’ pedagogies – deconstructing genres, situating texts in discourse communities, and reading like a writer – that each embody a paramount threshold concept in Writing Studies: writing is a social and rhetorical activity. GTAs’ responses indicate that these transformative reading lenses facilitate students’ ability to make reading-writing connections. When students engage texts through these lenses, the act of reading becomes a tool for shaping students’ current and future writing development.  相似文献

Abstract

Assessment rubrics intend to make criteria explicit to students. However, an understanding of assessment criteria requires tacit knowledge about which students may not be aware. The lack of such knowledge is notable in undergraduate health science students taking a compulsory course in the social sciences. This study performed a content analysis of how 1st year health sciences students interpret a SOLO assessment rubric for a sociology ‘reflection piece’ essay. The findings suggest that empiricism, standardisation and lack of tacit knowledge limit students’ ways of reasoning about the rubric. These limitations manifest in a methodical difference between students’ expectations and lecturers’ intentions of using a rubric. This difference is illustrated by the students’ need for procedural knowledge and the lecturer’s expectation of conceptual knowledge. These differences have implications for teaching, learning and assessment in health sciences undergraduate education. The findings also justify a dialogical approach to assessments through facilitating students’ epistemological development.  相似文献

Summaries

English

The report describes a study of the teaching behaviour of student‐teachers of science disciplines during the one‐term teaching practice of the English ‘Post‐Graduate Certificate in Education’ course, using the Science Teaching Observation Schedule by Eggleston et al.

The results suggest that in several behavioural dimensions, students and teachers achieve a close match. These dimensions, it is suggested, could represent the ‘stable’ elements in the students’ perception of science teacher behaviour learnt during their time as pupils, or they might represent ‘safe’ transactions which do not involve students extensively in problems of classroom management and control.

For other behaviour categories, it was found that students tended to behave less like experienced teachers as the training practice proceeded, but this was to some extent determined by the subject taught. Physics student‐teachers substantially maintained their similarity to experienced teachers, whilst chemistry and biology students drifted away. The nature of these drifts is discussed.  相似文献

Abstract

The study aims at investigating students’ learning/defence profiles. It also explores students’ profiles during different years of study. Participants comprised of 425 undergraduates. They completed the ‘Approaches to Study and Skills Inventory’ and the ‘Defense Style Questionnaire’. The students’ academic achievement was measured through grade point average. Cluster analysis revealed three profiles: ‘restricted maturity and dissonant-unorganized’ students, ‘defensive and reproduction oriented’ students, and ‘mature and learning advanced’ students. The profiles correspond to adaptive and maladaptive learning patterns. The study also revealed few (a) differences across the years of study (on strategic approach) and (b) interactions between the three clusters and the years of study (on mature defence style and GPA). The findings are discussed in relation to recent literature. Limitations and future research suggestions are presented.  相似文献

Abstract

This paper provides an overview and discussion of a study concerning student ideas about the terms ‘weathering’ and ‘erosion’. It describes the results of a survey conducted on 236 students, aged 16‐19, to ascertain details of their ideas about these two terms. The main factor students use to discriminate between weathering and erosion is movement. A majority of students appreciate that weathering occurs in situ, whereas erosion involves transport. Many students regard weathering as solely related to atmospheric elements, which results in some erosional and weathering processes being incorrectly classified. Human actions are perceived as types of accelerated erosion, but uncertainty surrounds whether animal activities are bio‐erosion or biological weathering. This uncertainty is also reflected in the literature. Taken collectively the results have a number of implications for teachers addressing these concepts and for the students they teach.  相似文献

ABSTRACT

What do secondary school students in Ontario, Canada, need to know about the world in which they live in? How did a secondary school ‘World Politics’ course that emerged in Ontario in the 1960s address this question? The ‘World Politics’ course that emerged in the 1960s clearly came about as a result of societal and educational developments. Educators in nineteenth-century Ontario felt no need for such a course. In more recent times, post-Second World War, the discipline of history underwent dramatic upheavals. The opportunities for new courses meant possibilities to reach out to new groups of students. Simultaneously, with this change, the importance of international relations in the history curriculum was reduced but this also allowed for its re-emergence elsewhere. Finally, ‘World Politics’ emerged as one of the responses to the need for an understanding of a much more complex world.  相似文献

ABSTRACT

It is widely argued that engineering education needs to change in order to attract new groups of students and provide students with knowledge appropriate for the future society. In this paper we, therefore, investigate and analyse Swedish universities’ websites, focusing on what characteristics are brought to the fore as important for tomorrow’s engineers. The data consist of text and pictures/photos from nine different Engineering Mechanics programme websites. Using a critical discourse analysis approach, we identify three societal discourses concerning ‘technological progression’, ‘sustainability’, and ‘neoliberal ideals’, evident in the websites. These discourses make certain engineering identities possible, that we have labelled: traditional, contemporary, responsible, and self-made engineer. Our analysis shows that universities’ efforts to diversify students’ participation in engineering education simultaneously reveal stereotypical norms concerning gender and age. We also argue that strong neoliberal notions about the self-made engineer can derail awareness of a gendered, classed, and racialized society.  相似文献
